Wild Garlic Allium Vineale

Description

Most aggressive of the Allium species. Unlike native Allium, it has leaves that are hollow at the base. Some species produce only flowers while other produce aerial bulblets. It has a strong flavor and odor when using as a garlic substitute.

Habit

Grass-like, bulb-forming perennial that emits a strong garlic or onion smell when crushed.

Leaves

Basal leaves emerge from bulbs and are 1/2-2 feet long and 2-10 mm wide, slender, smooth, hollow, and nearly round in cross section. Stem leaves are produced along the lower half of the stem, and are composed of a tubular sheath.

Stems

They are smooth, waxy stems are erect, unbranched, slender and rounded, and can grow from 1 - 3.5 feet high. Stems are solid and become rigid with age.

Flowers

Produced at the top of the flowering stems.

Greenish-white in color, small, and on short stems above the globe of aerial bulblets. Aerial bulblets are ovoid, often wholly or partially replace the flowers, and are usually tipped by a long, fragile slender green leaf.

Fruits and Seeds

Fruits are an egg-shaped, 3-parted capsule. Seeds are 1/8 inch long, flattened on one side, dull black and wrinkled.

Habitat

Native to Eurasia. Grows well in a wide variety of soils and is common in grain fields, pastures, meadows, lawns, gardens, and waste places, as well as along roads, rivers and streams.

Reproduction

Reproduces underground and by aerial bulblets, and less frequently by seed.

Native wild onion, sometimes called wild garlic (Allium canadense) can be distinguished by the fibrous-matted coating on the bulb, flattened solid leaves, star-shaped pink or whitish flowers and an onion-like taste. Wild onion also does not produce underground bulblets.

Monitoring and Rapid Response

Can be effectively controlled using any of several readily available general use herbicides such as

2,4-D or Dicamba.
